(color online) Schematic plot of electrical controllable spin valves based on a ZSR ferromagnetic junction. The C region is an undoped ZSR, the left (L) and right (R) electrodes are two semi-infinite ZSRs with different local magnetization M_L(R). The perpendicular electric field is applied on the C ZSR region, which can induce a staggered potential ηΔ_C and a weak disordered potential w_i between the A (red dot, η = +1) and B (blue dot, η = −1) sublattices of silicene. The width and length of the C ZSR are described by N and L_C, respectively.
